Win 10 poor performance on MacBook Pro Catalina 10.15.2

Post by Huti »

Hello,
I installed VirtualBox on my 2019 MacBook Pro with 10.15.2 Catalina. Installed win 10 64-bit. Generally everything work ok, I don't have crashes etc but windows works very slow. It doesn't run smoothly. Moving windows or files is very slow and stutter. In addition while Windows is running, MacBook works very loud and also is very hot. I installed all guests additions.

Attaching logs, hope somebody helps me.
Thank you!

I'm afraid the log has been truncated and is therefore not very useful. Please make sure to fully close down the VM before grabbing a log. But thanks for remembering to zip it.

I'm not seeing anything obvious in the log, e.g. your display size does not seem excessive. I would try reducing the vCPU count to 2 however, as assigning more cores than you need will definitely make a VM run slower. Also there are several recent topics in this forum dealing with Windows running slowely on OS X hosts - you should view them as well.

Thank you for the advice. I decided to try Parallels and now windows runs perfect. Please close the topic.
